2013-08-16 Fixed: Satellite imagery index files, script issue

The Actions script for adding satellite image tiles (Landsat CIRREF, Landsat MOS and RADARSAT) contain a redundant line, which may cause errors when trying to load tiles by using the Run Feature Action button and “Add full resolution image from local disk”. To avoid this, follow these steps for all of the three index files inside Quantum GIS:

1. Double-click the index layer in the Layers list, so that the Layer Properties window appears.
2. In the Actions tab, click once at the “Add full resolution image from local disk” entry in the Action list box, so that the Action properties box below displays the script.
3. In the Action box inside Action properties, remove this part of the script: “from os import startfile;”.
4. Click the Update selected action button below, then the Save as default button, and OK.
5. Save the project.

2013-08-16 Fixed: Satellite imagery index files, script issue

Saving your QGIS project file in another folder than the root of the Quantarctica folder, will make the Actions script for adding satellite image tiles (Landsat CIRREF, Landsat MOS and RADARSAT) not work. Follow these steps for all of the three index files inside Quantum GIS (Note that this will change the reference:

1. Double-click the index layer in the Layers list, so that the Layer Properties window appears.
2. In the Actions tab, click once at the “Add full resolution image from local disk” entry in the Action list box, so that the Action properties box below displays the script.
3. In the Action box inside Action properties, remove this part of the script: “from os import startfile;proj = QgsProject.instance();UriFile = str(proj.fileName());Path = str(os.path.dirname(UriFile));”.
4. In the “qgis.utils.iface.addRasterLayer…” part of the script, remove “Path+”
5. Insert the location of the Quantarctica Basemap folder on your disk, just before the “/Basemap/Imagery…” part, e.g. “C:/Quantarctica/Basemap/Imagery…”.
6. Click the Update selected action button below, (then the Save as default button) and OK.
7. Save the project.
